The Extrbici XF800 eBike Mountain Bike 1000W combines robust power with agile off-road capabilities, featuring a high-torque motor, long-range battery, and premium suspension. Designed for rugged terrain, it offers 28 mph top speeds, 60+ mile range, and military-grade aluminum construction. Ideal for trail enthusiasts seeking performance and durability in electric mountain biking.
How Does the 1000W Motor Enhance Off-Road Performance?
The brushless 1000W hub motor delivers 120Nm torque, enabling 35° hill climbs and instant acceleration. Its sine-wave controller ensures smooth power delivery across rocky inclines, while three assist modes (Eco/Trail/Turbo) adapt to technical singletrack demands. Overheating protection maintains performance during extended 2-hour ascents.
Advanced thermal management uses aluminum cooling fins and temperature sensors to prevent power drop-offs during sustained climbs. The motor’s 80% efficiency rating outperforms standard 750W systems, converting more battery energy into usable torque. Riders can toggle between cadence and torque sensors via the handlebar display, allowing precise control over pedal-assisted power bursts.
| Assist Mode | Torque Output | Max Speed | Energy Use |
|---|---|---|---|
| Eco | 60Nm | 20mph | 10Wh/mile |
| Trail | 90Nm | 25mph | 18Wh/mile |
| Turbo | 120Nm | 28mph | 28Wh/mile |
What Battery Technology Powers Long-Distance Rides?
Equipped with 48V 20Ah Samsung/LG cells, the XF800 achieves 68 miles in Eco mode (20mph avg). Fast-charging restores 80% capacity in 2.5 hours via IP67 waterproof ports. Battery management includes regenerative braking recovery and -20°C to 60°C thermal stability for alpine expeditions.
The modular battery pack features replaceable cell groups, extending overall lifespan to 1,000+ charge cycles. Smart balancing technology maintains voltage consistency across all 18650 cells, preventing capacity fade. Riders can monitor individual cell health through the diagnostic interface, with automatic load-shifting during high-demand situations.
| Riding Mode | Range | Charge Time | Regen Recovery |
|---|---|---|---|
| Eco | 68 miles | 2.5 hrs | 8% |
| Trail | 42 miles | 3 hrs | 5% |
| Turbo | 28 miles | 4 hrs | 3% |
Which Suspension Features Optimize Trail Comfort?
RockShox 35 Gold RL forks provide 150mm travel with rebound damping, while the DNM Burner rear shock absorbs root-laden descents. Adjustable preload accommodates 120-220lb riders. Hydraulic lockouts enable efficient climbs before descending 40% gradients with 4-piston Tektro brakes.
How Durable Is the Aerospace-Grade Frame Construction?
The 6061-T6 aluminum frame withstands 330lb payloads through triple welding at stress points. IPX5-rated components resist mud immersion up to 12″ deep. Stress simulations confirm 15-year structural integrity under repeated 2-foot drops onto granite surfaces.
What Safety Systems Prevent Trail Accidents?
Integrated 2000-lumen headlights illuminate 100-foot trails, while hydraulic disc brakes achieve 20mph→0mph in 16 feet. Tubeless Maxxis Minion tires with 2.5″ width provide 26psi grip on wet rocks. The anti-theft GPS tracker sends real-time location alerts via GSM networks.
“The XF800’s torque curve tuning particularly impresses – it maintains traction on loose scree where competitors spin out. The magnesium alloy pedals and sealed bearing hubs show Extrbici understands real mountain biking abuse.”
